Financial Attention
Review of Financial Studies · 2015-11-19 · 284 citations
articleOpen access1st authorCorresponding
This paper investigates financial attention using novel panel data on daily investor online account logins. We find support for selective attention to portfolio information. Account logins fall by 9.5% after market declines. Investors also pay less attention when the VIX volatility index is high. The level of attention and the attention/return correlation are strongly related to investor demographics (gender, age) and financial position (wealth, holdings). Using a new statistical decomposition,…

Grandma knows best: Family structure and age of diagnosis of autism spectrum disorder
Autism · 2017-02-08 · 40 citations
article1st authorCorresponding
This pilot study estimates the effects of family structure on age of diagnosis, with the goal of identifying factors that may accelerate or delay diagnosis. We conducted an online survey with 477 parents of children with autism. In addition, we carried out novel, follow-up surveys of 196 "friends and family," who were referred by parents. Family structure and frequency of interactions with family members have significant effects on age of diagnosis (p < 0.05). In all, 25% of parents report that…

Clinical signs associated with earlier diagnosis of children with autism Spectrum disorder
BMC Pediatrics · 2021 · 34 citations
1st authorCorresponding
BACKGROUND: The objective of this study is to gain new insights into the relationship between clinical signs and age at diagnosis. METHOD: We utilize a new, large, online survey of 1743 parents of children diagnosed with ASD, and use multiple statistical approaches. These include regression analysis, factor analysis, and machine learning (regression tree). RESULTS: We find that clinical signs that most strongly predict early diagnosis are not necessarily specific to autism, but rather those that…
